From fe69df40e5bdc715503be54a425fb26d493ce613 Mon Sep 17 00:00:00 2001 From: jshuao Date: Tue, 20 Oct 2026 20:04:38 -0400 Subject: [PATCH 1/4] Make True/False question generation more reliable - Ask for a "statement" field and a True/False statement package, so small models stop returning questions; reject items that are still phrased as questions. - When a generated package is rejected, regenerate it once and tell the model what was wrong, and log the reason as practice_question_validation_failed. - Credit evidence quoted verbatim from a different supplied passage to that passage, and ignore stray PDF spaces before punctuation. --- src/main/index.ts | 5 ++- src/preload/index.ts | 1 + src/renderer/src/practice-client.ts | 24 +++++++--- src/shared/bridge.ts | 1 + src/shared/practice-evidence.ts | 3 ++ src/shared/quiz.ts | 43 ++++++++++++------ tests/ui/practice.jsx | 4 +- tests/unit/typescript/practice.test.mjs | 38 +++++++++++++++- tests/unit/typescript/quiz.test.mjs | 60 ++++++++++++++++++++++++- 9 files changed, 157 insertions(+), 22 deletions(-) diff --git a/src/main/index.ts b/src/main/index.ts index ff4f48da..7829f59b 100644 --- a/src/main/index.ts +++ b/src/main/index.ts @@ -1,5 +1,5 @@ import type { IndexMaterialOptions } from '../shared/preparation' -import { preparationReportWithPython } from './python/python-engine-service' +import { preparationReportWithPython, writeTokenSmithLog } from './python/python-engine-service' import { app, BrowserWindow, dialog, ipcMain, nativeImage, net, safeStorage, shell } from 'electron' import { createHash } from 'node:crypto' import { existsSync, readFileSync, statSync } from 'node:fs' @@ -530,6 +530,9 @@ app.whenReady().then(async () => { ipcMain.handle('library:practice-sources', (_event, documents: StudyDocumentRef[], usedSourceKeys: string[], questionIndex: number) => practiceSourcesWithPython(documents, usedSourceKeys, questionIndex) ) + ipcMain.handle('practice:log-question-rejected', (_event, detail: { attempt: number;
